我正在使用Visual Studio 2017与Xamarin和Genymotion。 Visual Studio，Xamarin和Genymotion是最新的。应用程序仅针对Android 6.0创建。
在android manifest中我添加了android.permission.RECEIVE_BOOT_COMPLETED。
我在模拟器上使用“Wi-Fi”。
应用程序必须在设备启动后自动启动，并且只有在我重新启动模拟器时才显示错误。如果我手动运行应用程序一切正常。 该应用程序连接到IIS Web服务。
有没有人知道这里发生了什么？

根据我的理解，您的Android应用程序未授予互联网许可，或者您没有互联网连接，如果您没有权限，您只需在清单中添加此行
<uses-permission android:name="android.permission.INTERNET" />
